I saw an object with bright lights in the sky , at first i thought it was a airplane.But, it looked wird like it was a flying car, with it's headlights spaces exactly like a car.It was also "driving in the air'. The sky was pretty bright for 9:15 pm.

i could also see another craft in the air, and this was a plane i know. Because of O'hare there are a lot of planes in the sky all the time, and that is how i know that this craft lookes starnge. Also, as i was looking at it, it disapperared completely. On moment it was there, driving/gliding slowly in the sky, not very hight and not very fast, and he next it was gone! completely in one second, in a blink of an eye. But, the oher plane was still in the sky, i waited for couple of minutes, looked around in the sky, but it did not appear again. also, i know it is pretty cloudy today, but the clouds were too high and the plane too low to disappear into the clouds. And the lights completely disappeared. Also, there were no wing lights or any other lights other than the front headlights.

I call it a UFO, because to me it was an Unidentifed Flying Object (UFO), whether it was a conventional UFO or not! What is a conventional UFO? Also, i never did see the shape of the craft, which was weird because the sky was pretty bright, and i could see the shape of the plane behind.
